The Object.entries() method returns an array of a given object's own enumerable property [key, value] pairs, in the same order as that provided by a for...in loop (the difference being that a for-in loop enumerates properties in the prototype chain as well).

Syntax

Object.entries(obj)

Parameters

obj

The object whose enumerable own property [key, value] pairs are to be returned.

Return value

An array of the given object's own enumerable property [key, value] pairs.

Description

Object.entries() returns an array whose elements are arrays corresponding to the enumerable property [key, value] pairs found directly upon object. The ordering of the properties is the same as that given by looping over the property values of the object manually.

Polyfill

To add compatible Object.entries support in older environments that do not natively support it, you can find a demonstrational implementation of Object.entries in the tc39/proposal-object-values-entries (if you don't need any support for IE), a polyfill in the es-shims/Object.entries repositories, or you can use the simple, ready to deploy polyfill listed below.
